32 GRIESBACH : RAMKOLA AND TATAPANI COAL-PIELDS. 



gritty 'sandstones. No fossils were obtained in this section, but in the 

 same beds further westward several typical Panchet fossils were ob- 

 tained. 



The Mahadeva sandstone of usual type follows, but it is not clearly 



seen how this group is related to the underlying 

 Mahadevas. . i • • , . . . , 



Panchets m this section ; but it is certain that the 



general strike and dip is the same, and it may be assumed to be con- 

 formable. 



This succession of beds, dipping at about ^0° to west, remains tolerably 

 constant along the eastern part of the field and of the Pipraul-Sendur 

 escarpment, and there is no doubt the groups represent a natural boundary 

 of the field ; whilst south of the Sendur river, the whole series is cut off 

 by the great Tatapani fault, as is well seen in all the small nullahs, which 

 join the Sendur river from the south. 



The Mahadevas are somewhat disturbed near the fault, and some 

 remains of them are found in hills and isolated blocks south of the 

 fault, as, for instance, near Khijuria. The general dip of the Mahadeva 

 sandstone is about 15° to 20°, to west-20°-south, forming a high and pre- 

 cipitous escarpment facing east. 



North and north-west of the described sections, the dip of the beds 

 of Gondwanas gradually decreases, and as the strike turns round to the 

 west the bedding becomes almost horizontal.
